I have used a pair of Classe DR8 in mono with a Blue Circle 3.1 MK11 pre amp with CLS 11Z and this worked very well in a two chanel system.
I have also used the EAD Powermaster 500 on the CLS in 2 channel and in a complete ML system,in which the EAD drove 2 pair of CLS11Z and the Theatre Centre with no problems.
